Transmission problems

[Steele66]

So I just bought my 2016 eco diesel 2 months ago. I noticed about a month ago that the transmission temp was high at highway speeds. Like 260 degrees. It even reached 275 once and sent me a warning. I took it to a dealership and they told me they couldn’t find anything wrong with it.i have it back, and today I got a message for “service electronic throttle control” and it’s having issues accelerating. Any ideas if these are connected? Or how to solve either? I’m new to the diesel world.

clean the MAP sensor in your intake. Probably all caked in soot... not sure about the transmission issue, how's your coolant levels, could you be leaking coolant? search youtube for ecodiesel map sensor cleaning- some good vids of where it is and how to remove it, pretty easy to do.

Thank you! I will check into that before getting to a dealership and spending a bunch of money
